Pigs have a wide range of feeds and can be stocked after domestication.
First, stocking venue selection
The pigs are mainly stocked with wild fruits and wild grasses, and they mainly consider pastures rich in fruit trees such as hickory, mountain apricot, hawthorn, acorn, and bark seed as important breeding grounds. The stocking site should be far away from the villages and cultivated land to prevent the pigs from destroying the crops and the pollution of the villages.
Second, the construction of housing
As a forest area, there is a large temperature difference between day and night, and there are more rainy days in summer and autumn. When constructing a shed, it is necessary to fully consider keeping warm, keeping warm, sheltering from the rain, and using materials such as wood and weeds in the forest to choose leeward and high-lying terrain in the ravine. Drain easy place to build a simple housing for the pigs to rest at night. The area should not be too large, and a nest of piglets should be built in a circle. Each pig needs to build a house of 1 square meter.
Third, pig preparation before stocking
1. Do a good job of pig immunization, deworming, and castration. Before the pigs are stocked, they must complete the immunization work for swine fever, foot-and-mouth disease, blue ear disease, and piglet paratyphoid fever. After a few days of observation, when it is safe and healthy, it will be timely dewormed, castrated, carefully reared, and prepared for stocking.
2. The choice of free-range piglets. The piglets are fully inspected before stocking, captive and frail piglets are reared, and healthy, piglets weighing 11 kg to 15 kg are bred in groups, numbered, eared and managed as stocking pigs.
Fourth, stocking pigs feeding and management
1. Domestication at the initial stage of stocking. Under natural environmental conditions, pigs have the habit of colonization and swimming. If they do not domesticate, they will not be able to maintain the habit of being early and late, and will not be easy to manage. Therefore, during grazing, sows are used to lead the piglets, artificially let them from near and far, familiar with the environment, looking for weeds, wild fruits, and insist on feeding every afternoon, harvesting on time, using whistles, drums, etc. The way to return it to the pens, stimulate the pig to establish a response and form a conditioned reflex. After more than a week, you can develop the habit of returning to eat and rest in the evening.
2. Reasonable feeding. When the pigs are stocked, they are free to eat wild grasses and wild fruits. Under normal circumstances, it is not as good as the feeds used by the breeding and finishing pigs to provide comprehensive nutrition, and sometimes they are affected by the weather. In the process of grazing, we must carefully observe the nutritional value of the feed intake of weeds and wild fruits, and the amount of feed intake. According to the characteristics of long-bone long-flesh and long-fat fat of domestic pigs, formulas for supplementing diets are prepared. After the afternoon of harvesting, feeds are properly supplemented and the feed is fed to ensure that the stocking pigs grow normally and healthy.
3. Observe carefully. Abnormal conditions were found and dealt with promptly. Free-range pigs are allowed to eat freely in mountain forests. They have a large amount of activity, large changes in the weather, and are prone to getting diseases. Grazing staff should constantly observe the feed intake and mental status of each pig. From the aspects of pig's skin, color, coat cleanliness, lightness, walking speed, etc., determine whether pigs are healthy, find abnormalities, and treat in time to do their utmost to protect the pig's healthy growth and maximize pig production efficiency.
